ABB 2CDE601101R2001 EPD24-TB-101-1A Electronic Protection Device

The ABB 2CDE601101R2001 is an EPD24-TB-101-1A electronic protection device designed to provide selective overcurrent protection for 24 V DC load circuits. With a rated current of 1 A, active electronic current limitation and overload disconnection from 1.1 × In, it protects individual load branches against overload and short-circuit conditions.

The EPD24-TB-101-1A detects faults in individual branches and selectively switches off the affected circuit, helping prevent a fault from interrupting other load current paths. The device supports capacitive loads up to 20,000 µF and limits the maximum possible overcurrent to approximately 1.3–1.8 times the selected rated current.

Designed as a compact DIN-rail module, the ABB 2CDE601101R2001 has a 12.5 mm width and integrated potential-free auxiliary signalling. LED indication and a manual ON/OFF function provide convenient status control and fault identification in industrial automation and control-panel applications.

Key Advantages

  • Selective electronic protection for 24 V DC load circuits
  • 1 A rated current for control and automation loads
  • Active electronic current limitation during short-circuit conditions
  • Overload disconnection from approximately 1.1 × In
  • Selective shutdown prevents faults from affecting unaffected load circuits
  • Supports capacitive loads up to 20,000 µF
  • Maximum overcurrent limited to approximately 1.3–1.8 × In
  • Compact 12.5 mm-wide DIN-rail design

Selective 24 V DC Electronic Protection for Industrial Automation

The ABB 2CDE601101R2001 EPD24-TB-101-1A provides dedicated electronic overcurrent protection for individual 24 V DC load circuits. Its active electronic current limitation responds to short circuits, while overloads are disconnected from approximately 1.1 × In to provide selective protection of the connected branch.

Its compact 12.5 mm DIN-rail format makes the device suitable for space-constrained control cabinets. The integrated auxiliary contact, LED indication and manual ON/OFF function provide additional monitoring and operational convenience for industrial automation systems.

Typical Applications

  • 24 V DC control circuits
  • PLC and I/O power protection
  • Industrial automation control panels
  • Sensor and actuator supply circuits
  • Industrial instrumentation
  • DC control and signalling systems
  • Selective protection behind 24 V DC switching power supplies
  • Machine-control cabinets and automation equipment
